Propionic Acid, known scientifically as propanoic acid (CAS 79-09-4), is a saturated carboxylic acid with a molecular formula of C3H6O2. It is a colorless, oily liquid characterized by a pungent, somewhat unpleasant odor often described as reminiscent of body odor. Its physical and chemical properties make it a versatile compound with significant industrial relevance. As a key chemical intermediate and preservative, understanding its characteristics and sourcing is vital for various industries.

Industrially, Propionic Acid is primarily manufactured through two main routes: the hydrocarboxylation of ethylene, typically using nickel carbonyl as a catalyst, or the aerobic oxidation of propionaldehyde in the presence of metal salt catalysts like manganese propionate. Historically, it was also a byproduct of acetic acid production. These methods ensure a consistent and large-scale supply to meet global demand. For those seeking to buy Propionic Acid, understanding these production pathways can offer insights into purity and cost-effectiveness. As a manufacturer in China, we employ advanced production techniques to deliver high-grade Propionic Acid.

The applications of Propionic Acid are extensive and varied. Its most prominent use is as a preservative in animal feed and human food, where its ability to inhibit mold and bacterial growth is highly valued. It is also a critical intermediate in the synthesis of various chemicals, including plastics, rubber products, textiles, dyes, herbicides, and pharmaceuticals. The esters and salts of Propionic Acid also find specific uses, for example, as flavoring agents or antifungal agents in medicine. Its role as a chemical building block is fundamental to many manufacturing processes.
